With a thud, Ning Fan was the first to leap into the underground chamber.

His gaze swept over the Pill Furnace, noticing a piece of paper affixed to it.

Though the paper was slightly yellowed, a faint layer of the Law of Time covered its surface, preserving it through the ages without decay, with the writing still clearly visible.

After reading it, Ning Fan exclaimed in surprise, "This Pill Furnace was crafted by someone at the behest of the Falling Feather Demon Emperor, taking ten thousand years to forge. It is an excellent furnace capable of refining Grade-Ten Divine Pills and also serves as the demon emperor's battle treasure."
